I've about 150 different IPs like ... iptables -A block -s 155.161.173.128/26 -j ACCEPT iptables -A block -s 155.161.194.128/26 -j ACCEPT So, to make it easy for testing, you can do a loop like this ... for((i = 1; i < 100; i++)) do iptables -A block -s 10.0.0.$i -j ACCEPT done I'm running ThinkPad X61. Dual core T9300, 2.5GHz, 4GB RAM, 256GB SSD. No load as I was not running anything else, and X not running.
